Conversions (cm/sec to km/day)

An object travels at a speed of 7500 cm/sec. How far will it travel in kilometers in one day?

First, it is required that I have a unit plan
(Ex. mm -> cm -> meters)

Second, I must show the conversion factors
(Ex. 10mm/1cm, 100cm/1meter)

Third, I must perform and solve the problem using my conversion factors.
(Ex. They want me to convert 1meter to mm. Using my conversion factors, it looks like this: 1m x 100cm/1m x 10mm/1cm. The answer is 1000mm = 1meter)

*note: obviously, the example I used has nothing to do with the problem I am currently struggling with (the one in bold).

To solve the bold problem, I first need to come up with a unit plan... but I don't know how to with this one. Please help me
